When Apollo 11 landed on the Moon in July 20, 1969, some of oceanographers imagined global view of oceans from a satellite in a day. Since then, over 6000 satellites […]

The El Niño–Southern Oscillation (ENSO), the North Atlantic Oscillation (NAO) and the Indian Ocean Dipole (IOD) are primary sources of global and regional climate variability. Further understanding of possible connections […]

Atlantic multidecadal variability (AMV) of sea surface temperature (SST) is a key source of climate variability in surrounding regions. Low frequency Atlantic meridional overturning circulation (AMOC) variability is often invoked […]

Atmospheric noble gases enter aquatic systems by gas / water partitioning. Therefore, aquatic noble gas concentrations in waters reflect the physical conditions prevailing during gas exchange.  Consequently, applications of dissolved […]

Earth’s orbit and axial tilt imprint a strong seasonal cycle on climatological data. Climate variability is typically viewed in terms of fluctuations in the seasonal cycle induced by higher frequency […]

Anthropogenically-forced changes in the ocean are underway and critical for the ocean’s role as a carbon sink and marine habitat. Detecting such changes will require quantification of not only the […]

Part 1) The connections between South and East Asian Summer Monsoons have been a topic of research since decades. Several studies by the Chinese and the Indian scientists have documented […]

Based on the analysis of the observed Indian summer monsoon rainfall (ISMR) for the period 1871-2000, a 60-year cycle appeared to be evident. However, the decreasing trend in the ISMR […]

During the last 20-30 years, because of rapid economic growth, extensive areas of agricultural and rural land in many countries in Asia have been transformed into cities. Such changes have […]
